As one of the heavily discounted Playstation Plus titles I took a look at Cuboid and realised it was pretty much the same as one of the earlier games covered on Touch Arcade (like before iOS really took off as a gaming platform). I can't remember what it's called, but I do remember it was originally for BBOS.
I know it's been a long time since the question was posted, but for those interested.... Some that I like.... Nintaii 1 & 2, amtalee, rullaan, gears, edge, qvoid, ultimaze, get out 3, hippo gum, box roll 3d, crazy coffin, hydro tilt xl, diamond islands, of course cuboid, now available as paid and free. There are bunches of others. Some not very good. Most are just iPod or iPhone, but 2x ok for iPad.
